Frequently Asked Questions (FAQ)

• Why do I need a ModuleBus terminator? TB807 prevents signal reflections that can corrupt communication on long bus lines.
• Can I use TB807 with TB805 and TB806? Yes, it terminates any ModuleBus line with S800 series adaptors.
• Does it require external power? No, TB807 is a passive unit that draws no power from the system.
• How many terminators do I need per system? You need one TB807 at each physical end of the ModuleBus.
• Is TB807 compatible with all S800 I/O modules? Yes, it works universally across the entire S800 product family.
• Does it support hot-swapping? You can install or remove it while the system runs without causing issues.
• What is the maximum bus length with TB807 installed? We recommend up to 15 meters for reliable electrical ModuleBus performance.
• Do I need extra brackets for DIN rail mounting? No, the terminator clips directly onto standard 35 mm DIN rails.
• How does it perform in high-vibration areas? It meets IEC 61131-2 mechanical conditions, suitable for normal industrial vibration.
• Can I use it outdoors? Only indoors; IP20 and temperature range limit it to protected environments.
• What if I need technical support? Contact our team – we provide full application assistance.
